To all whom 'it may concern:

Be it known that I, ERNST GEORG BERN- HARD KRTING, a citizen of the Empire of Germany, residing at Mariendorf, near Berlin, Germany, have invented certain new and useful Improvements in Processes of Charging Upright Gas-Retorts; and I do hereby declare the followin to be a full, clear, and exact description o the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in a process for charging gas retorts, and par ticularly upright retorts, with coarse and fine materials; and the object of my improvements is to produce a perfect distillation of coals of different sizes and a rapid sepration of the gases produced, from the coa During the process of distillation, upright retorts must always be completely filled. Now, if such a retort is entirely filled with pieces of coal the gas' will readily escape through the passages formed by the coal. If, however, the retort contains only fine coal the spaces left for the escaping gases are small, so that a considerable pressure of gas is produced, whereby frequently a conslderable amount of gas is wasted, and furthermore the wall of the retort is bulged.

New, this invention consists in so placing the coal within the retort, that the coarse and fine parts are separately disposed within the retort, so as to form substantially separate pillars or columns, each of which consists of coal of substantially the same size, and which columns are in contact with cach other along a substantially vertical face and are exposed equally to the heat of the furnace. By this arrangement, a very uniform distillation of the coal is produced, and furtherxnore the gases distilled from the pillars or pillar of fine coal can escape upward through the adjacent pillar or pillars of coarse coal more readily, than when passing through thick layers of line coal.

To illustrate the invention an example of an, apparatus, whereby the process may be carried out, is shown in the accompanying drawing.

In the example shown, coal of ordinary constitution is taken from a` distant container a into a hopper car b from which it is discharged into a receiver d located above the upright retorts c, contained in an oven or furnace 1'. By means of a partition wall -low the receiver l I provide,

c, the receiver d is divided into two separate chambers f and g, one of which, for instance f, is designed to receive the coarse coal, while the chamber g receives the fine coal. Above the chamber g an inclined sieve h is provided, by means of which the coal falling from the hopper car b into the two chamber receiver d is automatically sorted, the coarse parts of the coal sliding into the chamber and forming one column while the fine coal passes through the sieve into the chamber g below said sieve and forms a substantially sc eparate column. The receiver is provided, at its bottom, with separate discharges adapted to be closed by a slide valve Beaccordinfr to the present invention, one or more distribut ing or charging funnels or hop ers m, mounted to travel on rails c and divided by a partition 'a into two compartments o and arranged in registry with the chambers f and g of the receiver d. Each of the compartments has its individual outlet, controlled by a slide g, the two outlets of each funnel being in registry with one of the sets of retorts c. To feed the different sets of retorts, some of the funnels or hopper-s m may be bent` to the left, and others to the ri ht.

As will appear from the rawing, tlie coarse and fine coal discharged into a distributing funnel displaceably mounted on rails will separately, but simultaneously pass into the retort c when the slide valve g is opened. They will therefore form adjacent substantially separate pillars of coal of different sizes within the retort which are in contact with each other along a substantially vertical base and are equally exposed to the heat of the furnace. Therefore, when the furnace is heated, the gas distilled from the fine coal will pass into the adjacent parts of the illar or column of coarse coal all over the iieight of the retort, and it will'rapidly escape upward through the spaces formed within the illars of coarse coal, whereby the danger of osing gas or of bulging the re torts is avoided.

Though for the purpose of explaining the invention an apparatus is shown in the drawing by means of which but two sizes of coal can be separately charged into the retort, it will be evident to those skilled in the art that, byV a simple modification, the apparatus can be adapted to charge more than two different sizes, and that the apparatus can be adapted to the requirements of different gas plants Vvvvitlnout (lepartin from tact with each other along a substantially the invention.
